This document explains how to install and configure the Intel® MPI Library for Linux* OS. Installation is a multi-step process. Read this document in its entirety before beginning, and follow the steps in sequence. For information about the product contents, including new and changed features, refer to the separate Release Notes.
If you have a previous version of the Intel® MPI Library for Linux installed, you do not need to uninstall it before installing this version. If you choose to uninstall the older version, you may do so before or after installing this version.
Before installing the Intel® MPI Library, you should check the Intel® Registration Center to see if a newer version or an update is available. The version on CD or as listed in your electronic download license letter may not be the most current.
Make sure that the following packages are installed on your system:
To install the Intel® MPI Library package on Linux* OS, do the following:
Upon registering for the Intel® MPI Library, you will receive a serial number
for this product.
Your serial number can be found within the email receipt of your product purchase.
Go to the Intel® Registration Center site
and provide the product serial number information. Once admission has been granted into the registration center,
you will be able to access the Intel® Premier Web pages for software support.
Extract the l_mpi[-rt]_p_<version>.<package_num>.tar.gz package by using following commands
# cp l_mpi[-rt]_p_<version>.<package_num>.tar.gz /tmp
# cd /tmp
# tar -xzf l_mpi[-rt]_p_<version>.<package_num>.tar.gz
The last command will create the subdirectory l_mpi[-rt]_p_<version>.<package_num>
(SDK only) Place the license file for the Intel MPI Library that is provided to you in /tmp/l_mpi_p_<version>.<package_num>. Do not change the file name as the ".lic" extension is critical. For instance, do the following:
# cd l_mpi_p_<version>.<package_num>
# cp <license key>.lic .
If you want to install the Intel MPI Library on all nodes of your cluster without using a shared file system, create a machines.LINUX file. Otherwise go to step 6.
The machines.LINUX file contains a list of the computing nodes (i.e. the host names) for the cluster, one hostname per line. The hostname should be the same as the result from the Linux* command "hostname". For example, if a cluster consists of four nodes, the file machines.LINUX might look like:
clusternode1
clusternode2
clusternode3
clusternode4
It is always assumed that the first node in the list is the master node. The remaining nodes are the compute nodes.
If you want to automatically establish secure shell connectivity between all nodes of the cluster, use the script file "sshconnectivity.exp". Otherwise go to step 6.
You can download the expect software package from the following URL: http://expect.nist.gov/
The syntax for the "sshconnectivity.exp" command is:
./sshconnectivity.exp machines.LINUX
This expect shell script will create or update the ~/.ssh directory on each cluster node mentioned in the machines.LINUX file. This script will prompt you for your password twice.
Enter your user password:
Re-enter your user password:
To provide security each time you enter your user password, asterisks will appear in lieu of the password text. Upon successful completion of the script, the following message fragment will appear:
…
*********************************************************************
Node count = 4
Secure shell connectivity was established on all nodes.
…
*********************************************************************
…
A log of the transactions for this script will be recorded in /tmp/sshconnectivity.<userid>.log,
where
Note that the sshconnectivity.exp script will remove the write access permission for your home directory for everybody but you. If this cannot be done, a password prompt will still be issued for any secure shell activity.
Execute the install script:
# ./install.sh
